Raspberry Pi 4 Model B is the latest product in the popular Raspberry Pi range of computers. It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior-generation Raspberry Pi 3 Model B+, while retaining backwards compatibility and similar power consumption. For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems. This product’s key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, 4GB of RAM, dual-band 2. 4/5. 0 GHz wireless LAN, Bluetooth 5. 0, Gigabit Ethernet, USB 3. 0, and PoE capability (via a separate PoE HAT add-on). The dual-band wireless LAN and Bluetooth have modular compliance certification, allowing the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market. Operating temperature: 0 – 50 degrees C ambient.

Title: Exceptionally Versatile and Affordable Mini Computer
Review: This was my first Raspberry Pi used for a robot kit. It won't be my last as there are a huge range of applications.Know that this is a completely bare computer. No power supply. No interfaces (keyboard, etc.) of any sort. No permanent storage. To actually set up the device you need a power supply, a mini SD card to act as the "drive," a keyboard, mouse and monitor.There are four standard USB connections (2xType3; 2xType2), two LAN connections and two MICRO HDMI connectors for monitors. There is a 30-pin bus affording power, switching and feedback for external devices. Wi-Fi and bluetooth are built in as is some sort of audio with a 3.5mm stereo jack provided.Downloading and installing Raspberry OS was simple and the device boots and resets very rapidly. The included apps are largely open source and functional.

Title: Good tiny computer
Review: Apparently these Raspberry Pi’s can be used for many different amateur radio projects. I used this one as a pistar to connect to YSF. It works as it should. I read that the 4s can generate a lot of heat so I have it placed on a small computer fan to keep it cool.

Title: The best single-board computer on the market
Review: I've owned many Raspberry Pi boards over the years, but the Raspberry Pi 4 is by far the most capable desktop-replacement board to-date. The wide software and documentation support within the community is phenomenal, making it extremely easy to get started with the device. Not to mention, the low price point makes it accessible to anyone who wants to experiment with computing.One of the most impressive features of the Raspberry Pi 4 is its easy-to-access GPIO pins, which allow for a variety of expansion options. This flexibility makes it a great device for hobbyists, students, and rapid-prototyping. The large ecosystem of expansion HATs offers endless expansion options.I primarily use my Raspberry Pi 4's as dedicated media center computers for Kodi, and they work flawlessly. The device runs smoothly and without any lag or stuttering, even when playing 1080p H265 videos. The small size of the device also makes it ideal for use as a portable media center, which is perfect for on-the-go entertainment.Overall, I highly recommend the Raspberry Pi 4 to anyone who is looking for a powerful and versatile computing device at an affordable price. Its wide range of capabilities, ease of use, and broad community support make it an excellent choice for anyone who wants to experiment with computing or build innovative projects

Title: Tired of using phone to view solar output and monitor battery?
Review: It's a cheap way to have a small computer. I use it to connect to my Victron 150/45 solar controller and view solar output on 13" monitor which is connected via wireless hdmi transceiver/receiver. The monitor is at one end of my RV while the solar stuff including the PI is at the other end. I loaded the Venus OS which actually took me a couple of days to understand and install. I watched a lot of YT videos. The wireless TX and RX can be found on Amazon for 20.00. I also made my own VE direct cable, more YT videos. All said and done I saved a few hundred dollars not having to pay for expensive Cerbo GX, but put in a lot of time which I have plenty of at age 66.
